BUILDING.

Application tiled `Inlay 27, 1925. Serial No. 33,0%.

lily invention has for its object the construction of a building in which one or incre of its floors are provided with drainage passages substantially parallel to the floor surface and draining into one or incre transverse conduits, and whereby communication niay be had with said .drainage passages from apparatus or machines at different places upon the licor by forming' coinn'ninin cation through the floor into the drainage passages wherever needed.

rlhe utility of iny invention is especially advantageous in buildings in. which large quantities of solutions are employed, such as in dye house equipments, and of which much waste fluids arise that have to be discharged to thesewer, niy improvements being adapted to permit removal of such waste 'linids 'without the clogging up of the floor space or the ceilings of the next floor below, with exposed pipes, etc. In inany raedern inanufacturing plants. the dye house equipment arranged in the upper floor of the building and iny improved `floor structure lends itself to perfect drainage, clean dry floors, unobstii'ueted working space and conlining all the passages and conduits within the floor so that they are practically unseen. lily invention also insures more free drainage area and easy access thereto than where nietal piping is einployed; and moreover, the floor structure inay be inade relatively light in weight, strong in its design, and practi* cally devoid. of instable fittings.

My improvements are adapted to buildu ings which are fornled of structural iron worl; with concrete floors and also for buildings inade entirely of reinforced concrete, and incre particularly, the invention consists in a concrete licor havii'ig a plurality of parallel drainage passages whose horizontal arcas equal a large part of the floor area above theni, said drainage passages opening at their ends into one or more transverse drainage conduits whose bottoni portions extend below the drainage passages und have coinnn'lnication with the drainage pipe or other nie-.ins for reinoval of the coilected fluids in said conduit and received from the drainage passages.

Mv invention also coinprehends details of construction whichytogether with the features above enumerated, are fully described hereinafter and more particularly defined in the claiins.

Referring to the drawings: Fi l is a vertical section through a floor portion of a building, elnploying structural iron worli and embodying my iinproveinens, talren ou line l-l of Fig. 2; Fig. 2 a vertical section of the saine italien on line ifi-m2 of Fig'. l; Fig. 3 a vertical section o the saine taken on line of Fig. Q; liie. if is a vertical Asection talten on line l---llJ of Fig. li, en'ibodying' my iinliirovenients as applied toa reinforced concrete building; and Fig. e is a vertical section talren on line time of liig. fl.

Referring to lligs. l, 2 and 3, which show iny improvements as applied to a building employing structural iron 'worlt with con crete floors, 20, 2l and 22 represent the posts, beains und girders of the structural iron work and what is shown is only by way of illustration and inay lvary according to the design of the building.

2 is the concrete floor structure having the lloor surface 3 and the lower layer 5 which may be reinforced by expanded or weven metal indicated at lo near the lower part and which would constitute the ceiling of the floor below. At one or more places, across the licor structure is av drainage conduit- 7 whose lower part 7a is preferably inclined to drain the fluid accumulations to waste drain pipes 11 and l2 leading to the sewer. The `draiinvge conduits 7 extend downwardly preferably below the level of the bottoni part 5 of the flooring, as clearly indicated in Fig. Q, and inay also open upward as at 8 to the floor level The upper edges of the openings 8 to the conduits are provided with longitudinal Z-shaped irons forming grooves in which removable floor plates l() are fitted. lily reinovii'ig the said plates l0, access is had to the interior oi the conduit for cleaning purposes when necessary. IThe iioor structure is provided with a plurality of drainage passages fl which Inay conveniently be forined of hollow tile arranged end to end in parallel relation in a plane substantially parallel to the surface il of the floor, and the ends ofthe said parallel drainage passages Ll open at G into the chainber 8 and by which they discharge into the drainage conduit 7. These drainage passages /l are preferably arranged on a slight incline, as shown, so that the flow by grav ity is insured with .discharge into the conduit. To prevent any escape of water or moisture downward frein the drainage passages to the ceiling portion 5 of the floor,

i) El len forms suspended from the structural iron Work, and these portions may be continued between the girders 22, as at 19, with the reinforcing expanded or other metal part- 16 so Athat the conduit 7 is strong -and durable. The interior of the conduits may be made l Water tight by use of asphaltum or other fdl suitable means familiar to the building trade, if sodeisired, and l do not limit myseit in matters ot details ot' this character. 14 indicates the luse of asphaltmn paper the Iupper walls oit the conduit about the-ends `oil the passages 4 and such paper protection may be extended downward into the lower conduit portion 7, it' so desired.

ils shown in Fig. 2, the cond uit 7 is transversely arranged with respect to the longitudinal alinement of the drainage passages -il and, moreover, drainage pas. are arranged upon opposite sides of the conduit and discharge thereinto,A so that each conduit 7 may'receijve drainage from a large numberl olfpassages 4 located at one side or both sides according to the general construction ol the building. In Fig. 1, moreover, it will be observed that where the structural iron lgirder 21 would block a continuation of the drainage conduit 7, the said conduit may be dividedwith the incline such that the liuid contents in the two sections would drain toward the girder and adapted to be drained ottl by the drainage pipes 11 which ,communicate with the common drain pipe 12.

Thedrainage passages 4 are arranged conveniently close to permitan aperture to be formed almost anywhere through the floor 2 for drainage into one or more or' the drainage passages, as shown at the upper right hand portion of Fig. 2, wherein an aperture is provided at 17 and through which a drainage pipe 18, leading from'the tanksl or vats or other source, may be extended. Similar openings may be made wherever the apparatus employed in the room may necessitate and in this manner permit immediate discharge of waste fluids .such as occurs in bleaching and dyeing establislnnents and others where waste fluids in quantity must begotten rid of.

It will be manifest that where immediate connection may be made with a drainage passage Within the floor structure that the general equipment in the room may be greatly simplified and, furthermore, that the necessity ot supporting from the ceiling of the tioor below ot numerous drain pipes may be entirely avoided so that not only is the room above the loor clear ot objectionable,

pipingadjacent to the floor, but similarly, the room below the floor may bc equally clear ot piping and suspension means adjacent to its ceiling.

Reierriuenew lo Figs. 1- and 5, the construction here shown correspomls in general particulars to that embodied in Figs. l. 2 and 3, but the improvements are shown iu connection with an all-concrete building, the presence of the iron structural work is omitted and in this case the conduits 7 may be continuous, so that only one drainage outlet 11 will be necessary for each conduit ol a reasonable length. Otherwise, the general features of construction are the same in respect to the drainage passages in the floor structure and their method ot communication with the conduits.

l'e'tcrring` however, to Fig. it will be seen that the drainage passages 4 are inclined to the right and to the left from pointl 4a, the waste tluid which passes to the righi discharging into another drainage conduit (not shown) which would be in parallel relation io and correspond in structure to the conduit 7. llnfronnection with such udditional conduit beingthe same as shown ai the lc'lt hand side oli said Fig. :'i (or Fig. ln this manner`r the length ol' the passages l may be a maximum and the number olI transverse drainage conduits a minimum for u lgiven lioor area; and in such an equipment. should the passage el; leadingr into one conduit 7 become clogged tron'iiany cause. the water would flow in the other direction over the high level and to the next adjacent conduit y thereby reducingl the possibilit)v of defective drainage.

It will now be apparent that lV have devised a novel and useful construction which embodies the tentures of advantage enumerated as desirable, and while l have in thc present instance shown and described the preferred embodiment thcreot which has been found in practice lo `give satistartor)v and reliable results, it is to be understood that I do not restrict n'lvself lo the details. as the same are susceptible of modiiicution in various particulars without departing from the spirit or scope oi the invention.
